4 rows by 3 cols matrix created, using rho ⍴ and iota ⍳. The 4 x 3 matrix is then stored in a variable named A. A is now reflected or flipped along its vertical axis as symbol ⌽ visually indicates. A is now reflected using the [1] axis indicator or first dimension modifier. The result is that variable A has been reflected across the ...
tidyr – help transform data specifically into tidy data, where each variable is a column, each observation is a row; each row is an observation, and each value is a cell. readr – help read in common delimited, text files with data; purrr – a functional programming toolkit; tibble – a modern implementation of the built-in data frame data ...
dplyr is an R package whose set of functions are designed to enable dataframe (a spreadsheet-like data structure) manipulation in an intuitive, user-friendly way. It is one of the core packages of the popular tidyverse set of packages in the R programming language. [1]
Even though the row is indicated by the first index and the column by the second index, no grouping order between the dimensions is implied by this. The choice of how to group and order the indices, either by row-major or column-major methods, is thus a matter of convention. The same terminology can be applied to even higher dimensional arrays.
The BigDecimal class in the standard library module bigdecimal has user definable precision. Scheme: R 5 RS encourages, and R 6 RS requires, that exact integers and exact rationals be of arbitrary precision. Scala: Class BigInt and Class BigDecimal. Seed7: bigInteger and bigRational. Self: arbitrary precision integers are supported by the built ...
APL (named after the book A Programming Language) [3] is a programming language developed in the 1960s by Kenneth E. Iverson.Its central datatype is the multidimensional array.
